. "Extra-pair fertlizations (EPFs) are common in socially monogamous passerines, but the contribution of EPFs to variance in reproductive fitness among males and to the evolution of secondary male ornaments\u00A0is unclear. To understand this issue, benefits from EPFs to females should be determined. This project focuses on understanding (1) how EPFs contribute to the variance in male reproductive success, (2) the signaling function of carotenoid-based feather ornament (%22good genes%22 indicated?) and its role in determining EP success of males, and (3) the benefits the females could obtain from EP matings (viability genes obtained?). The %22good genes as heterozygosity%22 and %22disassortative mating%22 hypotheses that differ in the expected contribution of EPFs\u00A0to the strength of sexual selection\u00A0will be evaluated. New microsatellites will be searched for to describe overall genome heterozygosity of individuals.\u00A0Complex studies, combining genetic, immunological and behavioral approaches to\u00A0provide complex picture"@en .
